PIPE-PATCH CLAMP.

To all whom it may concern lie it known that I, lVAmvIoK G BAT G, a citizen of the United States. residing at Cleveland. in the county of Guyahoga and State of Ohio. have invented a certain new and useful Improvement in Pipe-Patch Clamps, off which the following is a full, clear, and exact description.

This invention is an improvement in the kind of pipe leak closers which are adapted to clamp a sheet of packing material onto the pipe and over the hole therein so as to close the same.

The invention has for its special object to provide such a device in a form such that its lirst cost is small and. that the parts thereof when not in use may be so connected together as to occupy small space, and to insure that all of the parts thereof shall be at hand when they are required for use.

The invention consists in the combination substantially as shown of the two parts and 1% having lingers which are adapted to ii'iterlock when the device is in use, and when out of use, and the set screw, all substantially as herein shown and described and pointed out lt-il'initely in the claims.

in the (:lrawing. Figure 'l is an end view of the device showing the parts in the condition they will preterably occupy when the device is not. in use. Fig. is an end view showing the device in use upon a pipe which is sectioned. Fig. 3 is a plan view oi. the device as shown in Fig. 2.

te'l erring to the parts by letters, A and 13 rc resent two U-shaped clamping members. The larger member A. has at its ends the inwardly turned lingers (6. The smaller member 13 has at its ends the two outwardly turned fingers Z). The shape and size of these two parts are such that the member B may be turned so that it may be nested within the member A with its lingers b beneath the lingers a.

C represents the. 'lll screw which screws through the middle part of the member A. and by pressing against the middle part of the member 1, when the parts are nested as described, will hold them in the desired relation. \Vhen the parts have been so connected, the device occupies comparatively little space, and moreover all oit the parts thereol will be together when they are required lor use.

a leak in the pipe, the two members are separated and the smaller part 15 turned around. One member It goes over, and the other member goes under the pipe, and the lingers u and l) are interlocked as shown. A at rip o'l packing material .I) is placed between the member ll and the pipe; and the set screw (l is turned in against: the pipe with the result of securely t'astening the packing material over the leak in the pipe. The member Ii is preferably considerably wider than the member A, so that. it may cover a considerable length of pipe over which a crack may extend.

ll aving described my invention, I, claim:

.lhe combination oil: a U-shaped clamping member A having at its ends inwardly turned lingers, and a set screw (l which. screws through the middle part of said memher, and a smaller U shaped clannnng me1nber l3 having outwardly extended lingers, said member it being of such size that when turned and nested within the member A the lingers 0 will pass under the lingers a, and the set screw may be screwed in against the member 1% to hold the parts together.

In testimony whereof, I hereunto allix my signature in the presence o'l. two witnesses.
